+test_description='Test with test-tool submodule is-active
+
+This test verifies that `test-tool submodule is-active` correctly identifies
+submodules which are "active" and interesting to the user.
+
+This is a unit test of the submodule.c is_submodule_active() function,
+which is also indirectly tested elsewhere.
